FYI, at least some practitioners claim that there are different types of ADHD, which respond differently to different drugs.


1. Classic ADD
Symptoms: Inattentive, distractible, hyperactive, disorganized and impulsive. Normal brain activity at rest; decreased brain activity during concentrated tasks.
Cause: Dopamine deficiency; decreased blood flow in prefrontal cortex and cerebellum, as well as basal ganglia, which helps produce dopamine.

2. Inattentive ADD
Symptoms: Short attention span, distractible, disorganized, procrastinates, may daydream and be introverted; not hyperactive or impulsive; impacts girls as much or more than boys.
Cause: Dopamine deficiency; low activity in the prefrontal cortex.

3. Over-Focused ADD
Symptoms: Core symptoms of Classic ADD, plus trouble shifting attention, going from thought-to-thought or task-to-task; getting stuck in negative thought patterns or behaviors.
Cause: Dopamine and serotonin deficiencies; over-activity in anterior cingulate gyrus, which makes flexibility difficult.

4. Temporal Lobe ADD
Symptoms: Core symptoms of Classic ADD, as well as learning, memory, and behavioral problems, such as quick anger, aggression, and mild paranoia.
Cause: Abnormalities in the temporal lobe; decreased activity in prefrontal cortex.

5. Limbic ADD
Symptoms: Core symptoms of Classic ADD, as well as chronic low-level sadness (not depression): moodiness, low energy, frequent feelings of helplessness or excessive guilt, and chronic low self-esteem.
Cause: Too much activity in the limbic part of the brain (the mood control center); decreased prefrontal cortex activity, whether concentrating on a task or at rest.

6. Ring of Fire ADD (“ADD plus”)
Symptoms: Sensitivity to noise, light, touch; periods of mean, nasty behavior; unpredictable behavior; speaking fast; anxiety and fearfulness.
Cause: A ring of hyperactivity around the brain (the entire brain is overactive, with too much activity across the cerebral cortex and other areas).

7. Anxious ADD
Symptoms: Core symptoms of Classic ADD, as well as being anxious and tense, having physical stress symptoms like headaches and stomachaches, predicting the worst, freezing in anxiety-provoking situations, especially if being judged.
Cause: High activity in basil ganglia (the opposite of most types of ADD, where there is low activity).
